How to forward all requests on port X to localhost (Windows)
To forward all requests on a specific port to localhost on Windows, you can use the built-in netsh
command-line tool. Here's the general process:
Open Command Prompt with administrative privileges.
Run the following command to create a port forwarding rule:
kotlinnetsh interface portproxy add v4tov4 listenport=<source_port> connectaddress=127.0.0.1 connectport=<destination_port>
Replace
<source_port>
with the port number you want to listen on, and<destination_port>
with the port number on localhost where you want the requests to be forwarded.For example, to forward all requests on port 8080 to localhost port 3000, the command would be:
kotlinnetsh interface portproxy add v4tov4 listenport=8080 connectaddress=127.0.0.1 connectport=3000
Verify the port forwarding rule by running the following command:
kotlinnetsh interface portproxy show v4tov4
This command will display the active port forwarding rules, including the one you just created.
Test the port forwarding by accessing the
<source_port>
from another device or browser. The requests should now be forwarded to the specified<destination_port>
on localhost.
Please note that the port forwarding rule created using netsh
is not persistent and will be lost after a system restart. To make the rule persistent, you can create a startup script or use other methods to run the netsh
command automatically on system startup.
Additionally, ensure that your firewall settings allow incoming connections on the source port you specified. You may need to configure firewall rules accordingly to allow the incoming requests.
